Don’t have anything to comment on the rest, but my understanding with respect to: > I don't understand how Raft can scale writes or reads across multiple machines due to the round trip time talking to other nodes. Is that at the point where that becomes a bottleneck you scale to multiple clusters, where the read/write destination cluster is determined by a key and whatever your preferred hashing mechanism is.
